Turnberry Associates is an American real estate developer in residential, retail, hospitality and office. The company has developed more than $7 billion in commercial and residential property, including approximately 20,000,000 square feet (1,900,000 m2) of retail space, more than 7,000 condominium and condo-hotel residences, 1,500,000 square feet (140,000 m2) of class "A" office space and in excess of 2,000 hotel and resort rooms.

During the next 40 years, with their initial vision sketched on a cocktail napkin[citation needed], Soffer and Lewis built that land into what is now the City of Aventura. They developed Turnberry Isle Resort and Country Club, Aventura Mall, thousands of residential units and numerous office buildings. Aventura is now a self-contained city, known as a ‘City of Excellence,’[2] revolving around golf courses, lakes, bike and exercise paths and exclusive condominiums, hotels, shopping centers, office buildings, banks and more.
